Dear Felicia, Indeed, as pointed out by Mikhail, it must be your way of scoring in MGDRAW or the post-processing, not the physics. Attached you can find the results I calculated with your input file using the DETECT card. The results are pretty much the same as you get with Geant4 (for 1E6 primaries, like you used in Geant4).

DETECT 0.0 1.E-05 1.E-03 1.E-06 1. TARGETEDEP How do you process the MGDRAW, ENDRAW and EEDRAW entries within the user routine, and how do you process the collision tape itself? Both DETECT and user dump work fine for me. Best regards, Mikhail __________________________________________________________________________ You can manage unsubscription from this mailing list at
